AUTOMATIC GREASE-CUP.

Specification of Letters Patent.

Patented J an. 23, 1912.

Application filed October 1, 1909. Serial No. 520,494.

To all whom it may concern:

Be it known that. I, Jonx F. LEWIS, a citizen of the United States.residing at Philadelphia. in the county of Philadelphia 5 and State ofPennsylvania. have invented a certain new and useful Improvement, inAutomatic Grease-Cups, of which the follow ing is a specification.

My invention relates to a new and useful improvement in automatic greasecups, and has for its object to provide such a cup in which the greasewill befed by means of compressed aircontained in the upper portion ofthe cup, and yet when desired positively forced therefrom withoutcutting off the air p1-essui'e,'and in which the cup will always emptyitself.

With these ends in View, this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claims.

In order that those skilled in the art to which thisinvention appertainsmay understand how to make and use the same the construction andoperation will now be described in detail referring to the accompanyingdrawings, forming a part of this specification, in which- Figure 1 is aplan view of my improved cup, a portion thereof being broken away toshow the cap and cap tube therein. Fig. 2' a vertical section. Fig. 3 aplan View of the funnel. Fig. i a section of the funnel, at

of the removable cap and the tube carried thereby.

My improved grease cup consists of the body portion A. and the topportion B. The bodyportion being provided with internal threads C, whilethe top portion is provided with corresponding external threads D, inorder that they may be screwed together plainly shown in Fig i. A jamnut-w is also run .upon the threads I) and is adapted to be forced intocontact with the upper edge of the body so as to hold the portion B inany adjustment may be readily understood.

The lower portion of the body A is enlarged or swelled out as indicatedat F to form a multiple sided Wrench hold and also to produce anenlarged chamber. A threaded nipple G is formed with the bottom of thebody for screwing into the bearing to I be lubricated.

the line of Fig. 2 and Fig. 5 a plan view .11 represents a cappreferablymade of sheet metal, stamped into saucer shape hav' ingaflangewhich snugly fits within the top portion 15 and the tube 1 is secured inthis cap and projects above the same to form a stop to determine theposition of the cap in the portion B by coming in, contact with the topthereof, passes to the space above the cap when being compressed andflows back when being expanded.

J is a disk adapted to scrape the walls 01 the upper portion B in movingup and down therein and to this disk is secured the staple shaped wire Kthe latter adapted to slide into the tube and being prevented fromaccidental withdrawal therefrom by the pin L, thus permitting the diskto rest uponthe grease contained in the cup and maintain an evensurface.

M represents extends through the nipple its end being spun over, and thesides of this funnel and spout are corrugated or fluted as clearly showni Fig. 4 so as to leave passages from the lower portion of the cup tothe nipple, and holes 0 are formed in the spout of the tunnel for thepurpose hereinafter set forth: In practice after the body has beenfilled with grease the top portion is screwed therein, the disk comingin contact with the grease will be forcedupward into the top portioncompressing the air until the disk is stopped by the cap H, the spaceabove the cap acting as a reservoir for the compressed air. Any furtherdownward movement of the top Bwill force the grease through the tunnelto the bearing with screw pressure, but when the top 13 is stopped inany position the air compressed in the upper portionthereof will exertsuflicient pressure on ll'lrough this tube the air a funnel the spout bfwhich 1 the disk and grease to continue to feed the latter. edges of thedisk come in contact with the flange of the cap H the center portion ofthe disk also comes'in contact with the tube I thus supporting the diskagainst undue pressure. When a sufiicient amount of the grease has beenfed from the cup'to bring It is to be noted that when the the disk Jinto contact with the funnel the H and the disk+J the grease will not beforced intothe cap nor above it, thus leaving suflicient space to act;as an air-reservolr. The. ends of the wire K project belowthe disk andmaybe utilized to draw the disk downward should it become stuck in thetop;

Of course I'do notwish to be limited to I the exact details ofconstruction here shown as these may be varied within the limit of theclaims without departing from the spirit of my invention.

Having thus fully described my inVcntion, What .I claim as new anduseful, is

1Q A grease cup consisting of'a body and an upper portion the latterthreaded into the former, a removable cap set in .the upper portion, atube carried by said 'cap adapted to serve as astop, a disk, a guidewire secured to said i into said tube, means for preventing accidentalwithdrawal of the; guide wire, and

a funnel, the spout of which projects into the outlet from the bodyportion of the cup as specified.

disk and projecting.

2. In combination with a grease cup of] the character described, asaucer shaped cap adapted to be forced into the upper portion of thecup, a tube carried by the cap for determining the position of thelatter,

a disk, a, staple-shaped wire carried by the disk adapted to extend intothe tube, a funnel, thesides and spout of which are cor-.

rugated said spout projecting into the outlet from vthe body portion ofthe cup, as and for the purpose set forth.

3. In combination with a greasecup of the character described, a funnel,the spoutof which projects'into the outlet of the cup and is securedtherein so as to form a space outside of the funnel and its spout, thelower end of. said space being closed, said spout having a hole in itsside near its -lower end, the funnel and spout being corrugated topermit the passage of grease around the outside thereof, as and for thepurpose set forth. In testimony whereof, I have hereunto aflixed mysignature in the presence of two subscribing witnessesl JOHN F. LEWIS.
